RIGHT AND LEFT HAND sTo'vP'pAND -wAsTEooon SPECIFICATIKON forming part of Letters Patent No. 633,916, dated September 26, 1899. Application filed June 16 1899. S.erial1llo.'720,868. y(No model.)

To all whom it raw/y vcon/cern: f

Be itknown that LCHARLES F. SMITH, acitizen of the United States, residing in New Britain,in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements inRight and Left Hand Stopand Waste Cocks, of which the following y is a specication. i

My invention relates to improvements inright and left hand stop and waste cocks; and the objects of my improvement are simplicity of construction and convenience in operation. In the accompanying drawings, Figure 1 is -a rear elevation of my stop-cook. Fig. 2 isa sectional plan of the same, the plug and handie-stem being shown in horizontal section on the line a: m of Fig. 1. Fig. 3 is a sectional View, partly in elevation, the plane of section being indicated by the line y y, Fig. 2. Fig. 4' is a side elevation of a T-h'andle that may be used interchangeably` with the leverhandle shown in Figs. ,1 and 3. Fig, 5 is -a front elevation of my stop-cock vin a modied form. Fig. 6 is asectional plan of the saine, the plug and handle being shown in horizon- Fig. 7 is a horizontal section on' the line s s of Fig. 5, Vthe handle being removed. Fig. 8 is a sectional view, partly in elevation, the plane of section being indicated by the line t t, Figs. 6 and?.

The body A, pipe connections 5 and 6, and main portion of the tapering plug B, together with their various water-passages, are of an ordinary construction, the plug being held in placeby the usual nut 7'. 'Y

On the bodyA are two stop-shoulders 8,

and on the plug is a fixed pin 9 and aremovable stop 10, the latter being screw-threaded,

, while the plug is provided with two threaded stop -sockets 11 on diametrically opposite sides, into eitherone of which .the removable stop may be secured. The end of the plug is provided with a handle-socket 12, preferably of an angular form in cross-section, either with'or withoutthe side recesses 13, and the handle C isprovided with a stem 14, iitted to the said socket 12 and, if desired, provided with sidewebs or ribs 1,7 to fit the recesses 13, wherebyl the handle-stem can be inserted in the socket' in only two di-lerent positions, representing a half-revolution of the handle on the plug, in both of which the handle is parallel to the main passage 15 through the plug; The removable stop v10 in addition to itsstop function may serve asa set-screw for securing thev handle-stein in the plug. Two side faces of the fixed pin Vform fixed stops for engaging the stop-shoulders 8 on the bodyof the cock. The main passage and waste-passage in the plug are indicated by broken lines in Fig. 2, the said waste-passage .fixed pin will be in contact with one of the shoulders S on the body A and the removable stop will be midway between said shoulders, while the main passage throughthe plug will be closed and the waste-nozzle opened tc'drain the pipe thatis secured to the pipe connection l'when the handle and plug are in the position l 5, that being (with the adjustment shown) the house side. In order to change the cock for the other hand, it is only necessary to nnsorew and remove the removable stop, take out the handle, change its position on the plug one-half of a revolution, and then replace it and secure the' removable stop in the diametrically opposite socket from that in which it was before secured.

The .modification shown in Figs. 5 to'S is the same as theconstruotion herein before described excepting that I substitntefor the -fixed pinwith two vfaces for acting on the stops SY S a fixed'lug 9 with two faces in the body Afor acting on two stops of the plug BF, which's'topsA S are formed at the ends of theperipheral groove 1S in the said'plug and into which groove the end of the lug Sla projects. The relation of thelu g Jn tov the groove 18 and its ends or stops is such that when the handle and plug are set with the main passage 15 in line with the pipe connections thev plug'may be turned a quarter-revolution in either direction unless said movement is obstrueiled by the `removable stop. The operation is precisely vthe same as before, only the plu g is stopped with theremovable ystop inidway between hestop-shoulders S S by means ol' the fixed lug 9 of the body and fixed stops S of the plug instead of bythe sides of' the fixed pin of theplug` and lugs 88 of the body. The two sides of the fixed pin 5l in the first construction and the two ends' of the groovek 18 in the second construction constitute fixed stops of i the plug, and they both actvto stopr the plug in precisely the same relation to the removable stop lO.

I'have shown a lever-handle C in Figs. land 3; but, if desired,-the T-handle G2,Fig. 4, may

ybe inserted in the same socket in the same way, the shank ll being also formed to lit. the said socket. l In like man ner any desiredform of handle or operating device may be fitted to the plug for use therewithadler example,

a hydrant-rod handle-by merely providing the same with a stern 14 and, if desired, with a web or rib i7 to lit the soeket l2 inthe plug;

I am aware thateoeks have heretoforebeen described in several patents as having a plug provided with a socket and with handles provided With a stem fitted to said socket and*V held in place by a screw bearing on the Said stem, and the same is hereby disclaimed. I relaimvas my invention- 1. In a rightand left hand stop and Waste eoek the combination of the body provided with two stop-sheulders,the plug fitted to said body, and provided with fixed stops, a removable stop and dlametrically opposite sockets in the plnigifor alternately receiving the said removable stop, and a handle, substantially as described.

2. In a right and lefthand stop and Waste cock, the Combination of the bodyprovided with the two stop-shoulders, the plug fitted thereto,-havin`g a handle-socket and provided withxed stops and with diametrically oppositeseekets for receiving a stop, a removable stop adapted robe vse'turediin either of thek said stop-sockets-of the said plug, anda handle having a stemvitted te the handle-socket kof the plug and adapted to be fastened in place by the said removable stop, substantiallyas described; CHARLES F. SMITH.
